Kevin Systrom was fond of photography and obsessed about creating ​​a startup. After his third year at Stanford, he went to Florence to study photography and was given a 1982 Holga. This is a film camera which makes retro square pictures. They look cool with almost no effort from the photographer. This inspired Systrom to create a service that could create masterpieces from bad photographs. October 6, 2010, when Instagram appeared in the App Store, began the era of mobile photography. In 2012, Instagram was acquired by Facebook for $1 billion.

Today... we don’t even have to tell you! Just ask yourself: can you imagine the world without Instagram?
